in immediate proximity to the burner cap so.

as to efiectively preeheat the oil and provide for complete vaporization; the provision of a dead-air space as a component part of the burner cap in furtherance of the pre-heating principle; and the construction and arrangement of the various parts of the device to permit of ready and rapid disassembling.

To the accomplishment of the recited ob jects and others coordinate therewith, the preferred embodiment of my invention resides in the construction and arrangement shown in the accompanying drawings, hereinafter described and embraced in the scope of the appended claims.

In said drawings: Figure l is a top plan view of two of the burners embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a plan view of the burner and its tube removed. Fig. 4 is a perspective view of the burner and tube. Fig. 5 is a vertical sectional elevation of the burner cap and burner, and Fig. 5 is 'a transverse sectional view of the burner. Fig. 6 is a transverse sectional view taken along line 66 of Fig. 5. Fig. 7 is a detail vertical sectional elevation of the element which forms the deadair chamber in the burner cap. Fig. 8' is a top plan view of the base plate, and Fig. 9 is a transverse section thereof.

Generally speaking, my invention comprises a burner cap formed of top and bottom sections and an intermediate mixing chamber which cooperates with the latter to form a dead-air chamber. The bottom of the cap proper, which also constitutes the bottom of the dead-air chamber is made as is further carried out by the novel formation of the tube leading to the burner, the same running first upwardly then about the annular seat on the bottom of the burner cap,

. Y J thenreturnmg in a downward directlon,

and finally being disposed in parallelism with-the circular portion and in substantial continuity with the main lead portion of the tube. The burner proper islocated upon the last mentioned extremity of the tube, 1 1

and,- is provided with a novel form of needle valve which is easily accessible just to one side of the end of the base plate. The burner cap, burner and base plate are formed so that they may be readily dismantled when occasion requires, and in this particular it will be pointed out that the burner cap is preferably seated upon a plurality of uprights which extend from the base plate and that consequently the urner cap as an entiretymay be removed for obvious reasons from its normal position without necessitating the resort to manipulating fastening or attaching devices. i

In the drawings the numeral 1 designates the burner cap, which isformed of a lower cup-shaped section 2 and an upper convex baffle-plate 3, the two component parts being detachably secured together, as at 4:- The.

bottom section 2 is provided with a central circular opening 5 designed to receive a hollow shank portion or mixing chamber 6, the two being providedwith complemental thread portions to serve as securing means.

The mixing chamber 6 merges into an upper considerably reduced in thickness at this point. At the same time, 1 preferably extend the lower portion of the cap 2 to pre sent a shoulder 10.

As exhibited in Figs. 3 and 4 of the drawing it will be seen that the burner tube or pipe 11 has first imparted to it a right angular bend thus forming a' comparatively short vertical portion 12. The tube is then continued in the form of a coil, as 13, which is styled the retort or generator, and eventually terminates in a return bend 14: in close proximity to its companion bend 12. The tube is bent again in parallelism with the upper coil 13 as at 15 and projects a slight distance beyond the plane of said circular portion. Medially of the lower portion 15 I for this purpose.

I preferably mount a valve lfi which upon inspection of Figs. 5 and 5 will be -found to be formed of a vertical casing 17 with removable plugs 1'8 and 19 at opposite ends,

seen that the opening in the plug 18 may be regulated by simply oscillating the operating handle24 in the appropriate direction; that said opening may be kept clean at all times of foreign particles which lodge therein; and that the various parts of the burner are very accessible, due in particularlto the detachability of the upper and lower plugs 18 and 19.

As shown in Figs. 1, 2, 8 and 9, the burner cap 1 is simply seated upon the uprights 25 which extend from the base plate 26, the latter being formed to present shoulders 27 The retort will occupy a position in immediate proximi y to the shoulder of the bottom ot the burner cap and at the point where the latter is reduced and igniting the combustible mixture the resulting flame will pass upwardly and strike the upper baffle plate 3 of the burner cap and be deflected outwardly through the perforations 2 of'the bottom section of said cap. The mixing chamber 6, as well as the anemic opposite wall of the chamber 8 will quickly become heated and this will manifestly heat the air in said chamber to a very ltigh degree so that the oil contained in the retort will 'be vaporized before it issues at the burner, thus greatly aiding in the production of a highly efiicient combustible mix-. ture.

What I claim is:

1. In a device of the character described, the combination of a burner cap having a dead-air space therein, a mixing chamber contiguous said dead-air space, and aretort disposed in immediate proximity to and Within the limits of projection of said space.

2. Ina device of the character described, the combination of a burner cap having a closed chamber within said burner cap, a mixing chamber, and a retort disposed in immediate proximity to and within the limits of projection .of said hollow closed chamber.

3. In a device of the character described, .the combination of a burner cap, a hollow closed chamber within said burner cap, one \wall of said chamber being reduced in thickness, and a retort lying contiguous the reduced portion of said wall.

4. In a device of the character described, the combination of a burner cap having a dead air space therein, a mixing chamber contiguous said dead air space, and acoiled pipe retort having a discharge nozzle lisposed centrally thereof and discharging into said mixing chamber. a

In testimony whereof I hereunto affix my signature in presence of two witnesses. v
